I HOT-WATER HEATER.

Specification of Letters Patent.

Patented Mar. 20, 1917.

Application filed February 28, 1916. Serial'No. 81,045.

To all whom it may concern:

Be it known that 'we, WILLIAM GILLnsrIn CooNnY, both of the city of Toronto, in the county of York, in the Province of Ontario. Canada, have invented certain new and specification.

Our invention relates to improvements in hot water heaters and the object of the vention is to devise a heater which will have a maximum heating surface and in which all the heat units possible are utilized for the heating of the water and thereby economize the consumptionof fuel and it consists essentially of the following arrangement and construction of parts as hereinafter more par- Figure 1, is a general perspective view of our heater partially bfdken away and in sec tion..

Fig. 2, is. a vertical section extending from Fig. 3, is a plan station on line'wy Fig. 2.

Fig. 4, is a vertical sectional detail taken through the back flue of the heater and on line wy Fig. 2.

Fig. 5, is a plan. sectional view on line w y Fig. 2.

Fig. 6 is a perspective view of a detail.

In the drawings like letters of reference indicate corresponding parts in each figure.

1 indicates ghe base section forming the ash pit and on which the upper or heater section 2 is supported. "The heating section 2 comprises a'central cylindrical chamber 3 tapering from the bottom upwardly and opening at its lower end, such open lower end being set over on the open central portion 4; of the section 1. 5 indicate grate bars which are suitably supported in the open lower end of the chamber 3. 6 indicates a water chamber which surrounds the central chamber 3. 7 indicates a hollow head formed integral with the section 2 and with which the.upper end of the water chamber. 7 I

6 communicates at 8. 9 indicates a chamber which extends around the exterior of the chamber 6. 10 indicates a duct leading from the interior chamber of the fire potB to the exterior chamber 9 at the back of the heater. 11 indicates the fire door opening. 12 indi cates a duct leading from the fire door open ing through the chambers 9 and 6 into the fire pot 3. 13 indicates a water supply pipe extending through the exterior wall 9 of the useful Improvements in Hot-- 'Water Heaters, of which the following is the chamber 9 and through the exterior wall 1' of the chamber 6 so to the interior of the chamber 6. 14 indicates the outlet pipe for hot water which extends through the top wall of the head 7. 15 indicates a vertical flue extending up the back of the heater and provided with side walls 16 and 17. The side wall 16 extends the entire distance from the bottom of the chamber 9 to the-top of the chamber thereby entirely cutting oil communication from that side of the chamber 9 and the fine. The wall 17 extends downwardly from the top of the chamber to a point intermediately of the height thereof thereby leaving an opening 17 between the. flue 15 and the chamber 9. 18 indicates a bafile plate extending from the bottom of the chamber 9 to a point intermediately of its height so as to leave an opening at the top of the bafiie plate leading from one side to the other thereof.

19 indicates a baffle plate located at the opposite side of the heater in the chamber 9 and extending from the top of the chamber downwardly so as to form an opening 20 leading to the other side of the plate. 21 indicates the chimney opening. 22 indicates an opening formed in proximity to the top of the flue 15. 23 indicates a casing which is inserted through the opening 22 and secured therein and provided with perforations 24 at the bottom of its inner wall the advantage of having the inner plate perforated instead of bein entirely open is to re air so that it is given more tard the flow of time to heat and also to produce a more even distribution of the airover the fire. 25 indicates a slide damper for regulating the supply of air into the casing 23. 26 and 27 indicate clean-out orificesthrough which the interior of the chamber 9 may be gotten at to remove any deposits.

Having described the principal parts involved in our invention we will briefly describe the operation of the same.

Water passes into the, water chamber 6 through the inlet pipe 13. The hot gases pass upwardly from the fire pot 3 through the duct 10 leading into the flue 15 where they are mixed with the air injected into the upper end of the flue through the perforations 24 thereby forming a secondary combustion. The heat passes downwardly through the flue 15, through the orifice 17 and then passes upwardly in the chamber 9 over the upper end of the bafiie plate 18 and as to supply cold'water' will be seen that not only the interior surface of the water chamber 6 is subjected to heat from the fire but also the, exterior surface, the bafile plate directing the gases so that they travel over the entire surface of we have devised a very simple form ofheater which will present a maximum S1117":

;'the exterior of the water chamber. heated water rises upwardly in the chamber The 6 into the head 7 and passes out through the outlet pipe 14. p

From this description it will be seen that face to be heated to the action of the heating medium and which will utilize all the heat units possible for-the'heating of the water so that there will be absolutely no waste and will produce a heater of maximum capacity as none of the heat units can ossibly escape up 'the smoke pipe without first being utilized for the heating of the water.

copies of this pltent may be obtained for five cents each, by addressing the Commissioner of Eatentr i.

What we claim as ourinvention is:

In a hot water heater, the combination with the central chamber or fire pot, of a water chamber extending around the fire pot chamber, an exterior chamber extending around the water chamber, a vertical flue formed in the exterior chamberand having an opening in 'the bottom of one side wall, a duct leading from the top of the flue into the fire pot chamber, a chimney duct leading from the exterior chamber at the Opposite side of the vertical flue to the sidehaving the aforesaid opening, a double walled heating chamber located in the flue opposite the duct leading to the fire pot chamber and having a series of perforations in the inner wall thereof, and a suitable air regulating supply damper in the front wall of the double walled heating chamber.
